DPS 3000 is a 2 channel power amplifier that can handle exceptionally high power ratings in a compact and lightweight 2 rack units space.
Thanks to the class HD technology, this amplifier delivers up to 2 x 1700 W RMS @ 2 Ohm (3400 W RMS bridged @ 4 Ohm), weighting just 14 kg.
It comes with a ʽPFCʼ (ʽPower factor correctionʼ) switched mode power supply which ensures that a predominantly
resistive load is presented to the mains power supply; this also leads to an improved amplifier performance at high output levels. Thanks to its high efficiency heat sinks and variable speed DC fans, the DPS 3000 can withstand the hardest heat conditions ensuring great reliability.

LCD Screen: Backlit liquid crystal display shows speaker presets and signal
processing.
Signal Indicator: Green LED, one per channel, illuminates when a very low-level
signal is present at input.
?10 Indicator: Green LED fl ashes when output signal exceeds ?10 dB below
clip.
?20 Indicator: Green LED fl ashes when output signal level exceeds ?20 dB
below clip.
Ready Indicator: Green LED, one per channel, illuminates when the amplifi er is
ready to produce audio.
Clip Indicator: Red LED, one per channel, turns on at the threshold of audible
distortion.
Temp Indicator: Red LED, one per channel, illuminates under excessive temperature
conditions.
Power Indicator: Blue LED illuminates when the amplifi er has been turned on
and has power.
Rear panel controls and connectors shall include the following:
AC Line Connector: NEMA 5-15P (15A).
Input Connector: Two 3-pin removable Phoenix-type connectors each accept a
balanced line-level input signal.
Output Connectors: 4-position barrier strip with connectors for dual louspeakers
or bridge-mono loudspeaker.
